Overview
Sever?s Disease is used to describe pain in the back of the heel that comes from an inflamed growth plate in your child?s heel. Sever?s Disease commonly occurs in children from the ages 8-15. The muscles and tendons become tight as the bones shift and grow. This causes pain when walking or participating in athletic events that require running and jumping.
Causes
Heel pain is very common in children because of the very nature of their growing feet and legs. In children, the heel bone (the calcaneus) is not fully developed until the age of 14 or older. Until then, new bone is forming at the growth plate of the foot (the apophysis, located at the back of the heel), an area which is softer than others due to its role in accommodating the growth. Repetitive stress on the growth plate due to walking, running and sports causes inflammation in the heel area. Because the heel's growth plate is sensitive, repeated running and pounding on hard surfaces can result in pediatric heel pain. Children and adolescents involved in football, soccer, running or basketball are especially vulnerable. Over-pronation (fallen arches and rolling inwards of the feet) will increase the stress on the growth plate and is therefore a significant cause and a major contributing factor to heel pain in children.
Symptoms
Unilateral or bilateral heel pain. Heel pain during physical exercise, especially activities that require running or jumping. Increased pain level after exercise. A tender swelling or bulge on the heel that is painful on touch. Limping. Calf muscle stiffness first thing in the morning.
Diagnosis
All medical diagnosis should be made by taking a full history, examining the patient then performing investigations. The problem usually occurs in boys who are going through or have just gone through a growth spurt; one or both heels may be affected. Initially the pain may be intermittent occurring only during or after exercise. As the problem gets worse, pain may be present most of the time. There may be swelling over the back of the heel and this area is painful if touched or knocked. On examination the patient often has flat feet, very tight legs muscles especially the gastrocnemius.
Non Surgical Treatment
The disease itself is self limiting and will resolve regardless of treatment once the growth plate has fully closed. Depending on the age of the youth at onset this could be a problem for many years. Treatment has always been aimed at managing the pain as well as the inflammation. This is done with the rest, ice, non steroidal anti-inflammatories like ibuprofen, stretching, taping, heel cups, heel lifts and orthotics. In severe cases, cast or walking boot immobilization is used. Each of these have differing levels of efficacy but in my experience orthotics are the golden treatment or the silver bullet. I am not talking about your run of the mill over the counter Dr. Scholls shoe insert. These definitely have their place in the world but not here. Custom molded orthotics made from a mold taken of the youths foot will provide the necessary control and support to stop the pain cycle. We can safely report over 85% of patients who are able to get back to sports and other activities as long as they wear the orthotics in supportive shoes as directed.
Exercise
The following exercises are commonly prescribed to patients with Severs disease. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 1 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate, advanced and other exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head as far as you can go without pain and provided you feel no more than a mild to moderate stretch in the back of your calf, Achilles tendon or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Calf Stretch with Towel. Begin this exercise with a resistance band around your foot and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free. Once you can perform 20 repetitions consistently without pain, the exercise can be progressed by gradually increasing the resistance of the band provided there is no increase in symptoms. Bridging. Begin this exercise lying on your back in the position demonstrated. Slowly lift your bottom pushing through your feet, until your knees, hips and shoulders are in a straight line. Tighten your bottom muscles (gluteals) as you do this. Hold for 2 seconds then slowly lower your bottom back down. Repeat 10 times provided the exercise is pain free.
